Title: Manufacture of electron emitting element and image forming device using this element
Inventor: NAKANISHI KOICHIRO
IPC: H01J31/12
Filed: 1993-12-27
Abstract: PURPOSE:To provide a method of manufacturing an electron emitting element used in an electron source for an image forming device or the like. CONSTITUTION:In a method of manufacturing an electron emitting element having a thin film 4 containing an electron emitting element placed astride element electrodes 5, 6, when the thin film 4 containing the electron emitting part is formed, an organic metal thin film is formed, heated and baked to form the electron emitting part 3 in the thin film after heated and baked. In a process of heating the organic metal thin film baked, in the atmosphere containing an organic metal, after burning at less than a decomposition temperature of this organic metal, burning is performed at the decomposition temperature or more in the atmosphere containing oxygen, to form a metal oxide film. Thus by ensuring repeatability of an electron emission characteristic, an element with a small dispersing characteristic is obtained.

Title: Hemostatic valve for catheter introducer
Inventor: SAKAGUCHI YUKIHIKO
IPC: A61M25/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To eliminate the damage to a hemostatic valve at the time of insertion of a tube for medical treatment, such as catheter, into a blood vessel and to prevent the leakage of the blood by making the radius between adjacent slits longer than the radius on the extension line of the slits radially extending from the center of the hemostatic valve when the hemostatic valve is viewed from the upper surface. SOLUTION: Plural pieces (for example, 3 pieces) of the slits 5 extending in the radial direction from the center of the hemostatic valve 3 are formed at the front flank of the hemostatic valve. When the hemostatic valve 3 body is viewed from above, the radius R between the slits 5 is longer in shape than the radius (r) on the extension line of the slits 5. When the hemostatic valve 3 is built into a hemostatic valve built-in section which is a circular shape of the main body section of the introducer, the width (t) of the slits 5 is eventually closed. The radius R and the radius (r) have the difference above the width (t) of the slits 5 and below 0.5mm. As a result, the hemostatic valve is high in hemostaticity and the insertion of the tube for medical treatment, such as catheter, is safely and surely executed without the occurrence of cracks at the front end of the slits 5.

Title: Semiconductor memory device and its manufacturing method
Inventor: KUMAGAI TAKASHI
IPC: H01L27/105
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To provide an SRAM(Static Random Access Memory) which is so structured that a memory function is hard to be adversely affected. SOLUTION: A first buried layer 11 is formed below a P well 18 and especially under a region where the drain 36 of a driver transistor 30 is located and joined to a P well 18. The first buried layer 11 is formed under an N well 16 coming into contact with it. For instance, when the drain 36 of the driver transistor 30 is kept at a potential of 3V, α-rays penetrate through the P well 18, the first buried layer 11, and a silicon substrate 10, by which electron-hole pairs are broken up. As a PN junction composed of the P well 18 and the first buried layer 11 resides, only electrons contained in the P well 18 are attracted to the drain 36. All electrons attracted to the drain 36 originate from the P well 18, so that a drain voltage of 3V drops less. As a result, hold data are hardly damaged.

Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain a control method for driving an element and a scanning head capable of preventing color shift in an image even when a plurality of vibrations are generated in a driving mechanism in the case where an image is exposed or read by a plurality of elements attached to the scanning head. SOLUTION: A scanning movement of a scanning head is executed by a driving mechanism. A plurality of LED chips 80 arranged on the scanning head in the scanning direction exposes or reads an image. Adjacent LED chips 80 are provided such that a driving time difference for exposing or reading the image at an identical position between the adjacent LED chips 80 is set to be a value which is an integer multiple number of a least common multiple of a plurality of vibration cycles generated by the driving mechanism. As a result, it is possible to make each driving time difference to be an integer multiple number of the vibration cycle and make the amplitude of the vibration at the exposing by each of the LED chip 80 constant. Therefore, it is possible to completely superpose the exposing positions of the LED chips 80.

Title: Blowing method of air shower and air shower device
Inventor: HIRASAWA KOSUKE
IPC: F24F7/06
Filed: 1992-12-02
Abstract: PURPOSE:To increase dust removing effect by blowing air jet intermittently or pulsatingly. CONSTITUTION:When a visitor for a working chamber, maintained in a clean environment, has entered the shower chamber 4 of an air shower device 1, a fan 11 is operated to suck air in the shower chamber 4 and an air purifying chamber 5 to purify the air by a filter 13 and send out the same into an air chamber 10. In accordance with the increase of a pressure in the air chamber 10, clean air is injected intermittently into the shower chamber 4 through air injection ports 6, shielded intermittently by a shielding member 21, whereby dust and the like, adhered to the surface of the clothings of the visitor, is blown away. In this case, the pulsation and instantaneous increase of an injection pressure, which are generated by the intermittent air injection, increase the impact force of the air injection while turbulent flow of air, caused by the impact force of the air injection, provides the dust with shaking effect and weakens the adhesive force of the dust to the clothings of the visitor whereby the dust can be removed quickly. Accordingly prominent dust removing effect can be obtained by the air injection.
